IMPROVEMENT IN STOP-MOTIONS FIOR SPINNING-MACHINES.

Specification forming part of Letters Patent No. 58,226, dated September Q5, 1866.

To all whom it may concern Be it known that I, LEWIS CUTTING, of the city and county of San Francisco, State of Galifornia, have invented certain new and useful Improvements in Stop Motions for Speeders, Drawing Frames, and Other Machines for Vorkin g Cotton, VooLand Other Fibrous Material; and I do hereby declare the following description and accompanying drawings are sufficient-to enable any person skilled in the art or. science to which they most nearly appertain to make and use my said invention or improvements without further invention or experiment.

The nature and object of my invention and improvements are to secure by certain improved mechanism the throwing; off of the belt and stopping of the machine when the sliver 0f fibrous material breaks or runs out.

In the accompanying drawings, Figures l and 4l are side elevations, and Figs. 2 and 3 are end elevations, of the parts of a machine showing my improvements.

In these drawings a portion of a roller-beam is shown with myimprovements.

B is part of a back drawing-roller, mounted in a proper stand, and `carrying a side cam,s, to vibrate the leverIJ on the pivot R. (Shown in Figs. 2 and 3.) This lever P is connected by the link O to the slide` N, which it traverses, and the slide N has a notch in its under side, fitted to the rib M on the bar J, so that the slide N will traverse the bar, which is arranged to traverse freely in the brackets K K, as shown in Figs. 1 and 4, the weight of the slide N being sufficient to hold the notch on the rib and traverse the slide, unless it is opposed by some obstruction. v

A is a trumpet or guide fastened to the wire OD, which is bent at a right angle and fitted to vibrate in the stand E, fastened to the rollerbeam, and the wire GD is bent again at a right angle, asshown at H, Figs. 2 and 3, so that when the trumpet A is in the position shown in Fig. 2 the end H will be out ofl the way of the pin a in the under side of the bar J, so that the bar is free to traverse 5 but if the sliver of cotton or wool breaks or runs out of the trumpet, it falls t0 the position shown in Fig. 3, and brings the end H up to the under side of the bar J, and the pin c strikesthe end H, which stops the bar J, and the slideN rises on the rib M to the position shown in Fig. 4, and lifts the end of the locking-lever W and releases the rod T, so that the spiral spring U traverses the rod T, which is connected with the belt-shipper, and throws the belt oft', and stops the machine until the attendant pieoes up the sliver in the trumpet to hold it in the position shown in Fig. 2,and runs on the belt to start the machine, and in doing so traverses the rod T so that the lever W catches into the score d and locks the rod and the slide N assumes its position on the rib M and traverses the bar J again until the sliver breaks or runs out, when the apparatus throws the belt off again, as above described. The lever W vibrates on the pin f in a stand fastened to the roller-beam, and the rod T traverses in a stand fastened to the rollerbeam, and is provided with a score, d, in which the lever W catches to lock it aud hold the rod and belt-shipper.

What I claim as my invention and improvement in above-described stop-motion is- The bar J and slide N, combined and operating substantially as and for thc purposes described.

In witness whereof I have hereunto set my hand and seal this 29th day of November, A. D. 1865.
